, adjustal'jle t0 accsmnmtlate labels are Wl .ch they are I pivotally mo untmay be taken by the label-.conveyers, by a pusher comprising an arcuate plate 90, which is concentric with the main shaft 22 and is slidable over the bottom of the label box 84. The plate 90 is afiixed to the inner end of a feed-screw 92, which extends through the outer wall of the label box and is, threaded through a feed-nut 94, having ratchet teeth on its periphery; The ratchet teeth coiiperate wit a feed-pawl 96 carried by a oke 98 rotatable on the feed-screw 92, and a so with a locking-pawl 100, which prevents backward rotation of the' feed nut. A finger 102 depends from the yoke 98 in a position to engage a yielding stop 103, carried'by a post 104 on a shelf 106, whereby a feeding movement is imparted to the pawl 96 when the label holder is moved forward,

as will be hereinafter explained. A retractile spring 108 is afiixed at one end to the yoke 98, and at its other end to a bracket 110 onthe label box 84. This spring returns the yoke and pawl after the feeding movement, said return movement being limited by an adjustable sto stop determines the extent to w ich the feeding nut 94 is turned at each feeding movement of said nut. The label box is mounted upon a carriage having upwardly extending sides 114, and a bottom 116. A pair of rollers 118 ,are rotatably mounted on the bottom 116 of the carriage, and travel over the shelf 106, which is supported by posts 120, mounted on the table 20. The carriage is braced by a strut 122, which is affixed at one end of the carriage bottom 116, and at its other end to a collar 123 loosely surrounding the shaft 22. A retractile spring 124 is attached at one end to the carriage bottom 116, and at the other end to theshelf 106.

X With the parts in the position shown in Figs. 1 and 2, the interior of the conveyer 3'1 is in communication with the vacuum chamher 70, and a label is drawn from the stack 80 against the perforated facing 'sheet 38 of said conveyer. At this time the cam roller 48 has entered the depression 49 in the cam ring 50, causing the label conveyer to tilt so that its arcuate face is inclined to correspond with the inclination of the stack oflabels 80. A projection 130 on the flan e 44 is in engagement with a detent 132 pivoted upon an upright 114. The detent 132 is normally held in the position shown in Fig. 9 by a retractile spring 134.

The label-conveyer 31 and the label-holder or box travel together until one end of a rod 112. 'This 7 of the detent 132. When the rod 136 chgages the stop 138, the wedge-shaped end of said rod engages the arm 142 to raise the detent 132 out of engagement with the projection 130. At this time the cam-roll 48 has passed out of the depression 49 into engagement with the circular periphery of the cam ring 50, the label-conveyer being thereby swung 'into vertical position, and the label-box 82, being freed from the projection 130, is swung back to normal position by the spring 124. At the end of the forward movement of the label-holder the feed nut 94 is given a partial turn, by the engagement of the members 102 and 103, to feed forward the stack of labels. The label held by the label-conveyor is then moved to the adhesive-applying position. The mechanism for applying the adhesive to the label will next be described. It comprises a tank 150, filled with paste 151, and mounted upon a bracket 152, which is secured to the table 20. A paste-roll 154 is partly immersed in the paste 151, and is mounted upon a shaft 156, ournaled in suitable bearings, said shaft being provided with a gear 158 which meshes. with a gear 159 on a stud shaft 160. The shaft 160 has a bevel gear 162, which meshes with a bevel gear 163 on a vertical shaft 164, said vertical shaft having a sprocket wheel 166 over which a sprocket chain 168 asses. The chain 168 is driven by' a sproc et wheel 170 on the main shaft 22. .A plate 172 is adjustably mounted on the tank 150 and is adapted to regulate the amount of the paste taken up by the pasteroll 154. The paste-roll 154 is in peripheral contact with a series of conical paste-transferring rolls 174, mounted on a shaft 176, whereby the paste is transferred from the roll 154 to a paste-applying roll 178, with which the conical transferring rolls are also" in peripheral contact. The paste-applying roll 178 is mounted upon a stud shaft 180 and is adapted to apply the paste to the label as it is carried by on' the label-conveyer.. The periphery of the roll 178 is formed with shallow grooves or corrugations 182, and aplurality of deeper grooves 184. The grooves 184 are adapted to receive wire fingers 186, which project laterally from a post 188 mounted on a bracket 190. The fingers 186 are so shaped that they lie within the grooves 184 at the point of tangency between the paste-applying roll and the label as the latter moves along with the label-conveyer. Beyond this point of tangency the fingers 186 are bent so that their ends 192 project beyond the periphery of the paste-applying roll. These ends are adapted to engage the label to prevent it from following around the periphery of the paste-applying roll, and said fingers guide the label so that it will remain on the conveyer. The paste-coated label is then moved from the stack 80 by the suction in the con-- by the conveyer into engagement with a container 194 restin upon a latform 196'. The container, to which the la el is to be atiixed, engages a yielding facing 197 on an arcuate plate 198, which plate 18 mounted upon. a pair of springressed rods 200 slidablv mounted in brac ets 202. When the/labelconveyer engages the container 194, the latter is given a rolling motion along the padded plate 198, and the label is wrapped about the container, the facing 197on the plate 198 and the facing 38 on the labclconveyor impartin a yielding pressure to the label to apply t e latter smoothl to the periphery of the container. When t e label arrives at the container 194, communication is shut off between the label-conveyor and the vacuum chamber 70, by the nipple 59 passin from a position over the slot 68 t0 the so id portion of the plate 69 extending between the ends of said slot, see Figs. fraud 6. Thus the suction is removed from the label and it will adhere to the container as they move'along together. After the label is afiixed to the container, the latter is left in the position indicated by 194, and then the conveyer passes along to the label-holder or box 82, where another label is drawn veyer, it being understood that the pipe communicating with the conveyor casing is now again in communication with the vacuum chamber through the slot 68.

In order to move the containers away after they have been labeled, 1 provide a dog 210, carried by a lever 212 fulcrumed at- 214 on the under side of the platform 19%. The lever 212 is provided with a depending finger 216, which is adapted to be engaged by a beveled projection or canrfinger 218 carried by the flange 44. When the finger 216 is engaged h a canrfinger 218, the lever 21:2 is pushed along an inclined strap 220, mounted on the under side of the platform 196, and the dog 210 is projected through a slot in said platform, and caused to engage the container 194 to move it and those ahead toward the rightinto a position when: 5 they will be brought. into engagciincnt with a movable wiper in the form of a bolt 124. When the finger 216 is disengaged from the cam-finger 212%, the lover 2i; is returned to normal position by a spring 226.

The wiper may be of any suitable con-- 1 struotion, and as here shown comprises an endless belt traveling over pulleys M8 and 229, on shafts 230 and 5232, respectively. The shaft 232 is provided with a. grooved i pulley 2 4 Over which a belt 236 passes to a. grooved pulley formed on the sprocket wheel 170. Cooperating with the 'lpQl belt 3:2 is a stationary wiper, comprising a plate .338 having a yielding facing 240 and aiiixed to rods242, which are slidably held in bracketsi 244 mounted on the platform 96. The rods 1 242 are surrounded by springs 246, by which the plate 238 is yieldingly pressed against I the containers so that they will be fed forward by the belt 224, and the stationary and movable wipers cooperate to wipe the abels so that their ends will be pasted down tightly and smoothly on the container.

What I claim is 1. In a labeling machine, the combination of a label-holder adapted to hold a stack of labels, a label-conveyor adapted to remove the labels one at a time from said holder, means for applyin paste to said label, a support for the article to be labeled, means for engaging the article and. cooperating with said conveyor to enable the latter to affix the label to the article, means for wiping the labels after they are aifixed', and an oscillatory member projecting through said support for engaging the articles and feedthem to the wiping means. In a labeling machine, the combination of a label-holder arranged for oscillatory of a label-holder arranged for oscillatory motion, a plurality of label-conveyers arranged to be swung one at a time into operative relation with said holder to remove a label therefrom, means for causing the conveyor and holder to travel together while the label is being removed, means for swinging the conveyor into upright position, means for returning the holder to normal position, means for applying paste to said label, and means cooperating with said conveyor to enable the latterto apply the label to an article.
